Answer: See explanation
Step-by-step explanation:
The perimeter of a pentagon is gotten through the summation of its five sides. Let the first side be represented by x. Since each side of a pentagon is 10 cm greater than the previous side, then the sides will be:
First side = x
Second side = x + 10
Third side = x + 10 + 10 = x + 20
Forth side = x + 30
Fifty side = x + 40
Therefore,
x + (x + 10) + (x + 20) + (x + 30) + (x + 40) = 500
5x + 100 = 500
5x = 500 - 100
5x = 400
x = 400/5
x = 80
Therefore, the lengths will be:
First side = x = 80cm
Second side = x + 10 = 80 + 10 = 90cm
Third side = x + 20 = 80 + 20 = 100cm
Forth side = x + 30 = 80 + 30 = 110cm
Fifty side = x + 40 = 80 + 40 = 120cm

BRAIN PLS
Answer:
1) element - a member of a set
2) inequality - <, <, ,
3) line graph - visual tool used to illustrate solution sets
4) real number - positive or negative, rational or irrational numbers including zero
5) set - a collection or group of sets indicated by brackets, {}
6) set builder notation - a shorthand way to write a set
Step-by-step explanation:
The definitions of each of the terms are as follows:
Element: In a set, each member is called its element.
Inequality: The term inequality is used to compare two values. The sign used for inequalities are <, <, , .
Line graph: It gives the solution on a number line. This is the pictorial or visual representation of the solution.
Real number: All numbers that are rational, irrational positive or negative values are called real numbers.
Set: A set is a collection of data that are enclosed in two curly brackets. The data can be numbers, sets, etc.
Set builder notation: It is a shorthand notation used to represent a given set. It defines the data inside the set using appropriate mathematical symbols.
Answer:
500
Step-by-step explanation:
just multiply 50 by 15 and get 750
and then multiply 50 by 25 and get 1250
then do 1250-750 and get 500 cause thats the remaining area
